NAME         top

       sd_bus_get_name_creds, sd_bus_get_owner_creds - Query bus client

SYNOPSIS         top

       #include <systemd/sd-bus.h>

       int sd_bus_get_name_creds(sd_bus *bus, const char *name,
                                 uint64_t mask, sd_bus_creds **creds);

       int sd_bus_get_owner_creds(sd_bus *bus, uint64_t mask,
                                  sd_bus_creds **creds);

DESCRIPTION         top

       sd_bus_get_name_creds() queries the credentials of the bus client
       identified by name. The mask parameter is a combo of
       SD_BUS_CREDS_* flags that indicate which credential info the
       caller is interested in. See sd_bus_creds_new_from_pid(3) for a
       list of possible flags. On success, creds contains a new
       sd_bus_creds instance with the requested information. Ownership
       of this instance belongs to the caller and it should be freed
       once no longer needed by calling sd_bus_creds_unref(3).

       sd_bus_get_owner_creds() queries the credentials of the creator
       of the given bus. The mask and creds parameters behave the same
       as in sd_bus_get_name_creds().

RETURN VALUE         top

       On success, these functions return a non-negative integer. On
       failure, they return a negative errno-style error code.

       Returned errors may indicate the following problems:

           An argument is invalid.

           The bus cannot be resolved.

           The bus has already been started.

           The bus was created in a different process.

           Memory allocation failed.

NOTES         top

       These APIs are implemented as a shared library, which can be
       compiled and linked to with the libsystemd pkg-config(1) file.
